Method for producing a contactless ticket and ticket and ticket obtained by means of said method

摘要

A multi-step method for producing contactless tickets or cards, the tickets or cards including a chip (24) which is connected to an antenna (10) on a paper carrier. The method includes: printing the antennae in series on the paper carrier strip using a silkscreen ink; fixing a chip to each ticket by connecting bond pads of the chip to the antennas' bond pads (14, 16); and covering the paper strip, including the silkscreen-printed antenna and the corresponding chip, with an adhesive paper strip. After each step, the paper carrier strip is wound up before the next step is begun. Each of the silkscreen-printed antennae is coated with a protective layer (12) to prevent silkscreen ink from being transferred to the back of the paper carrier strip during the successive winding-up following each step.
